Is median used for when there is a wide range of numbers?
If the wide range is evenly spread between the very small and the very large (the distribution is symmetric) then there is not much to choose between the median and the mean. If not, the median will have some advantages as a measure of central tendency.
What is the definition of spread math?
Spread, in the context of a probability distribution, is a measure of how much the data vary about their central value.
Which graph shows spread and range of all values in a set of individual data values?
A distribution function or a cumulative distribution function. The spread and range are also immediately apparent from a box [and whiskers] plot.
What does standard deviation tell about distribution?
How widely spread out, or tightly concentrated about the mean it is.
How can the measures of center and spread of a bimodal distribution be described?
By specifying the centre and standard deviation of the distribution but also mentioning the fact that it is bimodal and identifying the modes.

Why in a normal distribution the distribution will be less spread out when the standard diviation of the raw scores is small?
The standard deviation (SD) is a measure of spread so small sd = small spread. So the above is true for any distribution, not just the Normal.
What standard deviation tells us about a distribution?
It is a measure of the spread of the distribution: whether all the observations are clustered around a central measure or if they are spread out.
Why is the mean the standard partner of the standard deviation?
The mean and standard deviation often go together because they both describe different but complementary things about a distribution of data. The mean can tell you where the center of the distribution is and the standard deviation can tell you how much the data is spread around the mean.
What is spread?
In a statistical sense, spread, otherwise known as statistical dispersion, is one of various measures of distribution.
The spread of something over a given study area is?
distribution
What is the difference between a population distribution and sampling distribution?
Population distribution refers to the patterns that a population creates as they spread within an area. A sampling distribution is a representative, random sample of that population.
What is the definition of spread math?
Spread, in the context of a probability distribution, is a measure of how much the data vary about their central value.
What does standard deviation tell about distribution and varity?
It is a measure of the spread of the distribution. The greater the standard deviation the more variety there is in the observations.
What is population geographic distribution?
It is the amount of population spread throughout an area.
Which graph shows spread and range of all values in a set of individual data values?
A distribution function or a cumulative distribution function. The spread and range are also immediately apparent from a box [and whiskers] plot.
What type of population distribution is displayed by penguins?
A uniform population distribution occurs when penguins are spread evenly across breeding grounds.
